LM293DT datasheet by STMicroelectronics

LM293DT Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM293DT can handle?
  The LM293DT can handle input voltages up to 40V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the output voltage is stable and regulated?
  To ensure a stable output voltage, make sure to use a suitable input capacitor (e.g., 10uF) and output capacitor (e.g., 22uF) as close to the device as possible. Also, ensure the input voltage is within the recommended range.
• What is the minimum input voltage required for the LM293DT to function?
  The minimum input voltage required for the LM293DT to function is around 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM293DT in a high-temperature environment?
  The LM293DT is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliable operation.
• How do I protect the LM293DT from input voltage surges or spikes?
  To protect the LM293DT from input voltage surges or spikes, consider adding a transient voltage suppressor (TVS) diode or a voltage clamp circuit at the input.
